Question :- What is the area of a triangle with a base of 15 inches and a height of 4 inches ?

A. 15 square inches

B. 30 square inches

C. 60 square inches

D. none of the above

Solution :-

Triangle :--- is a plane figure with three straight sides and three angles.

→ Area of ∆ = 1/2 * Base * Height = 1/2* ab* sinC = 1/2 * bc *sinA = 1/2 * ca* sinB = √( s(s-a)(s-b)(s-c) ) [ where s = (a+b+c)/2 ]

given that,

• Base = 15 inches .
• Height = 4 inches .

then,

→ Area of ∆ABC = (1/2) * Base * Height

→ Area of ∆ABC = (1/2) * 15 * 4

→ Area of ∆ABC = 15 * 2

→ Area of ∆ABC = 30 inches² . (B) (Ans.)
